IN"ENTOR i mamga N WITNESSES: Q WM E ran STATES PAEN MEIJI NAKAMIZO, or san FRANCISCO, CALIFORNIA CARRIAGE-TOP.

To all whom it may concern citizen of the UnitedfStates, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Carriage-Tops, of which the following is a specification. w

This invention relates to a carriage'top. It is one of the objects of the invention to provide a simple, substantial carriage. top of the folding type suchas is used on automobiles, andthe like, and particularly to provide a construction which will permit a single person to .raise or fold the top without any assistance.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a side elevation showing the top raised. Fig. 2 is a horizontal section on rear endsof thechannel bars is the rear bow 4 of a folding top, generally indicated at C, and formed on eachbar in alinement with said pivots is an extension bracket 5 which is adapted to receive the front bow "6 when the top is folded back, as indicated in Fig. 3. The lower ends of the front bow are each provided with an outwardly extending bearing pin 7, and these pins. arefadapted to be projected through the extension brackets 5 and secured therein by means of cotter pins 8. 3

The front end of each bar is perforated,

as at 9, and the pins 7, on the lower ends of the front bow, aresimilarly adapted to "be projected through said perforations, as in dicated in Fig. 1 and secured therein, by

cotter pins Swhen the top is raised.- The channel bars are each provided with ingress and egress openings9' and 10 respectively,

Be it known that I, MEIJI NAKAMIZO, a

ing the top may now walk The front braces 16 Patented Au 3, 1915.

and each channel i curved outwardly as at 11, near the rear end and inwardly, asl at 12, near the front end for purposes here? furthermore, partly covered'by a'flange 13 inafterto be described. Each channel, is,

to form a guide for the-pins 7,01', in other words, to prevent the ends of the bow fromjumping out of the channel bars while beingmoved from one end ofthe barto the other.

The operation will'be as follows :When it is desired to raise the top, it is accomplished by firstremoving the cotter pins 8 from pins The tendency of this how is to spring outward and the ends will, therefore, when released, have to be pushed a slight distance forward until pins 7 have entered the partlyv covered channel sections. The person rais machine and lift the top up, causing the rear bow 4 to assume a vertical position, while the front bow will be caused to slide forward on the channel bars, as indicated by dotted lines at 15, Fig. 1. The front bow may now be pulled completely over to the front end of the bars and will here spring out through openings 10, causing pins 7 to be projected through the perforations 9 where they may be secured by the cotter pins 8. may now be opened and the guy straps (not here shown) attached to secure the top in its raised position. I i

The slight curve formed in the channel at each end of the bar is provided for the following reason: After the front bow is released with relation to the rear supporting brackets 5 and the lower been inserted in the channel, everything is ready and the top may be raised. The raisends thereof have to the rear of the ing of the top causes the lower ends of the bow to slide forward in the channels, as in- Fig. 1. The curve the tension in the i dicated by dotted lines in indicated at 11 permits bow to be partly released, thereby permitting the bow to slide forward with the least friction possible. The curve indicated at 12 forces the lower ends of the bow inward again, increasing the tension tocsuch an ex tent that whenvtheends finally enter opening 10 they will immediately spring out,

causing pins 7 to enter perforations 9 with out any outside-assistance. I i

The bars aremade in sections 32, and 34; to permit the door 35 to be opened at any time. The bhrs;constructed as here? shbwn are simple" and substantial in construction and may be easily attached or built'in any may be used in connection with the bars and Practically n f onstruction m y, b mployed. 7 The important feature isiithilt: the P'Tvisibn: f' the bars lTlalis "it possible for one pefson to reise or.close the top Without any outside' asslstance.
